JOINT m in tension and compression, another object of the invention being to efiect improvements in the means for joining the covering material of the wing in conjunction with the jointed main win beams, in order to preserve that p strength of cantaliver hich carries part of the beams.
In'the type of aeroplane supporting sur; as cantaliver or internally face known (i. e. supporting surfaces for planes in which the neceSsa provided b the structure of the planes or of I to the other parts or to the structure of the body of the aeroplane that they may be readily detached, it has been founddifijcult joint between the sald parts of suflicient strength and of sufii'ciently' low weight to be efiiciently used in anaeroplane. f plane where the mainly provided beams or other parts of'the remainmg structure.

t will be understood from the foregoing t at my improved aeroplane wing beam joint is exceedingly strong and at the same le of sustaining or enduring successfully all the compression or tensilestresses to which it may be subjected either duringflight or in landing. In further accordance with myinvention in the case of a, wing constructionin which it is desired tovconnect not only the beam .ends but also the covering material 17 of the the ends of the beams of the types herein-- before describe and the edges of the coverabut at the wing joints are form integral hinge memwhich hinge ins, or pintles as indicated twoparts of the wing,

by the While I have herein shown and described the preferred embodiments ofmy invention, I would have it understood that changes may I be made in the form, proportion and construction of the several parts without de-..
arting from the spirit of my invention and within the scope of the appended claims. What I claim is 1 1. In an aeroplane wing, beam members arrangedwith their ends spaced apart and provide with longitudinal spaced slots forming laminations a coupling device between the ends of the beam members and having spaced laminations'arranged in the slots thereof. 7
2. In an aeroplane wing, beam members arranged with their ends spaced apart, and a coupling device securing said ends to-' between said slots, and
gether, said beam members and cpupling device having laminations arranged in mutual contact and alternate relation.
"3. In an aeroplane wing, wooden beam members arranged with their ends spaced apart," and a coupling device securing sai ends together, said beam members and a metallic coupling device havinglaminations arranged relation.
4. In an aeroplane'wing, beam members arranged with their ends spaced apart and provided with longitudinal spacedslots forming laminations between said slots, and a coupling the beam members and having spaced laminations arranged in the slots thereof, said coupling devlce comprising detachable mem- V bers.
5. An aeroplane wing com rising detach; able sectionseach including am members and a covering, coupling devices between the ends of said beam members,-and detachin mutual contact and alternate g device between the ends of able hinge connections between the meeting edges of the coverings.
